COMPUTATIONAL FLUID DYNAMIC ANALYSIS OF PRODUCT MOISTURE RATE’S IN THE SOLAR ENERGY DRYING SYSTEM
Abstract
In this study, a food drying system with air heated solar collector is designed. In the designed drying system, the apples are dried. Moisture content (MCk), drying rate (DR) and humidity (MR) values of dried apple slices were calculated. In the experiments, dehydration of the dried apple slices was simulated by the numerical analysis program. The model is designed for drying analysis. In the first case, the diameter of the apple slice is 60mm, the thickness is 14mm and the surface temperature is 4°C. The inlet temperature of the drying air is 56.4°C and the air velocity is 1.6 m/s. The velocity and time, moisture content and temperature change data of the dry matter were compared with the available experimental studies. The values obtained as a result of the simulation and the experimental studies were similar.
